Penetrometer Electric H-1240.4F Humbolt


For complete test  procedure ( s ), refer to the following specifications: ASTM D5, D217, D937, D1168,  D1321,  D1403,  D1831,  and  AASHTO T49.


1  Level the instrument carefully by means of the leveling  screws on the base, sighting the spirit level from above, in order to obtain accurate alignment. After the instrument has been leveled, avoid  shifting its location.

2  Position  the height of the supporting casting by turning  the knurled  travel nut on the main support post  and  then  tighten the black knob.

3  If additional weights are used, these should  be taken  from the side post  and set on the end  of the plunger ( opposite end  of the needle chuck ).

4  Insert penetrating needle  or cone  into chuck and  tighten the chuck screw.


1  Holding  the plunger with one  hand, squeeze the lever on the front of the support casting with the other to allow raising the plunger & needle to clear the sample. Flip the toggle switch on the front panel to the up position and pre-select the specified time of penetration by turning  the knobs  on the timer bezel.

2  To conduct a test  set the needle, cone  or micro-cone on the sample surface. When ready  to begin, press  the red pushbutton on the front panel to release the plunger for the pre-selected amount time. The timer- controlled electromagnet will immediately release the plunger and  after the preselected time interval will re-grip  it to stop  the test.

3  Measure the travel of the plunger assembly by lowering  the dial indicator rod to contact the plunger and observing the dial reading.

4  To reset for the next test, the front panel toggle switch must first be flipped to the down position, then the above sequence can be repeated.

CAUTION : Keep  hands,  clothing and other  objects away from moving parts when  the machine is in operation.
